Sanskrit:
एष मे बह्वसाधूक्तो वधोपायाश्च निर्मिता: ।तैस्तैर्द्रोहैरसद्धर्मैर्मुक्त: स्वेनैव तेजसा ॥ ४५ ॥
ITRANS:
eṣa me bahv-asādhūktovadhopāyāś ca nirmitāḥtais tair drohair asad-dharmairmuktaḥ svenaiva tejasā
Translation:
Hiraṇyakaśipu thought: I have used many ill names in chastising this boy Prahlāda and have devised many means of killing him, but despite all my endeavors, he could not be killed. Indeed, he saved himself by his own powers, without being affected in the least by these treacheries and abominable actions.
